Justin wrote in to tell us about the new firmware he wrote for Arduino –

Breakfast is a firmware which runs on the Arduino allowing all of itâ€™s functions to be accessed by a computer over a serial connection. I have implemented most Arduino functions ver batim, and I do plan on adding the rest soon. For now I have written a ruby â€œlibraryâ€ which allows you to access Breakfast, as a proof of concept, I have implemented an Arduino Shell using this library and Interactive Ruby IRB.

And who doesn’t love serial for breakfast – this sounds very awesome, and could be a great way for beginners to get the hang of programming in small line-by-line pieces. Check out his site for the deets – Breakfast, serial for Arduino
